  Power Supply 

The L860 module should be powered through the +3.3V pins, and the power supply design is shown in 

Figure 3-2: 

 

Figure 3-2 Power supply design 

 

The filter capacitor design for power supply is shown in the following table:

Description   

220uFx2 

Voltage-stabilizing capacitors   

Reduce power fluctuations of the module in 

operation, requiring capacitors with low ESR.     

 

LDO or DC/DC power supply requires the 

capacitor of no less than 440uF 

 

The capacitor for battery power supply 

can be reduced to 100-200uF 

1uF, 100nF
